Enter the total number of cats and the total area (miles^2) into the Calculator. The calculator will evaluate the Cats Per Square Mile. 

Cats Per Square Mile Formula

CPM = C / SM


  • CPM is the Cats Per Square Mile (cats/mile^2)
  • C is the total number of cats
  • SM is the total area (miles^2)

To calculate Cats Per Square Mile, divide the total number of cats by the area in square miles.

How to Calculate Cats Per Square Mile?

The following steps outline how to calculate the Cats Per Square Mile.

  1. First, determine the total number of cats. 
  2. Next, determine the total area (miles^2). 
  3. Next, gather the formula from above = CPM = C / SM.
  4. Finally, calculate the Cats Per Square Mile.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of cats = 8000

total area (miles^2) = 1222


What factors can affect the number of cats per square mile in a given area?

The number of cats per square mile can be influenced by factors such as the availability of food and shelter, the presence of predators or competitors, human population density, and local policies on stray and feral cats.

How can the cats per square mile metric be useful for animal welfare organizations?

This metric can help animal welfare organizations identify areas with high densities of cats that may require targeted spay/neuter programs, rescue efforts, or public education campaigns to manage and support the cat population effectively.

Are there any limitations to using the cats per square mile formula for estimating cat populations?

Yes, this formula assumes an even distribution of cats across an area, which may not be accurate in urban versus rural settings. It also does not account for the dynamic nature of cat populations, including birth rates, death rates, and human interventions.

Can the cats per square mile formula be adapted for use with other animals or in different units of area?

Yes, the formula can be adapted for any animal population by changing the unit of count from cats to the animal of interest. Similarly, the area can be measured in square kilometers or hectares instead of square miles, with appropriate adjustments to the formula.
